LITTER-CARRIER.

\ Specification of Letters Patent.

Patented Apr.-9, 1912.

Application filed August 28, 1909. Serial No. 515,106.

This invention relates to overhead car riers for conveying litter or any other desired material from place to place by gravity.

One of the objects of the invention is to provide a novel form of bucket having improved means for locking it in a predetermined relation to its supporting frame.

Another object is'to provide simple means whereby the bucket can be unlocked at any desired point, the unlocking being automatic and resulting in the inversion of the bucket so as to cause the contents thereof tobe dumped.

A further object is to provide improved means whereby the supporting wheels of the carrier will remain in contact with the cable or track, even though the said carrier be tilted with respect to the cable as, for example, when the carrier is given an initial push to start it upon itsjourney.

With these and other objects in view, the invention consists in certain novel features of construction and the combinations of parts hereinafter more fully described and pointed out in the claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :-Figure 1 is a side elevation of the carrier and a portion of its supporting cable, a part of the receptacle and its lock being broken away. Fig. 2 is an end elevation thereof. Fig. 3 is an enlarged section on line AB, Fig. 1.

Referring to the figures by characters of reference, 1 designates a top bar having hangers 2 extending downward from the ends thereof. These hangers and bar form a main frame. Each of the hangers is pivotally engaged by a trunnion 3 extending from one end of a trough-like receptacle 4 which is open at the top. One of the trunnions extends through the center of a disk 5 secured in any suitable manner to one end of the receptacle, said trunnion being arranged concentric with the disk and the disk being provided with an annular flange 6 having a notch 7 therein. This notch is designed to receive a locking stud 8 extending laterallyi from the lower end of a rod 9 which is slidably mounted in the top bar 1 and also within a guide sleeve 10 which is secured to one of the hangers 2. A forked head 11 is secured to the upper end of rod 9 and carries a roller 12 which is located directly below and close to the cable 13 constituting the supportof the carrier. A coiledspring 14: is mounted on the rod 9 between bar 1 and head 11 and exerts a constant upward pressure upon the head so as to hold the stud 8 normally seated within notch 7.

Hangers 15 are secured upon the top bar 1 adjacent the ends thereof and each hanger is provided at its upper end with a hooked portion 16 carrying a grooved wheel 17 de-. signed to bear upon the cable 13. Longitudinal slots-18 are formed in the hooked portion of the front hanger 15 and these slots receive the trunnions 19 of the front wheel 17. A retaining block 20 is secured to the front hanger below the cable 13 and at a distance therefrom equal to the length of the slots 18.

It is tobe understood that the notch 7 is so located that when the stud 8 is seated therein, the receptacle 4 is held against movement relative to the hangers 2 and slightly tilted off center, as shown in Fig. 2. When the carrier is given a push to start it, the front end thereof on which the locking mechanism is mounted will tend to swing upward relative to the supporting cable 13, but, 1n view of the fact that slots 18 are provided, the front wheel 17 will remain upon the cable. Block 20 limits this upward tilting movement by coming into contact with the cable before the wheel 17 can leave it. A cam-like projection 21 may be secured to the cable at the point where it is desired to dump the contents of the receptacle and when the carrier approaches this point, the roller 12 will ride against the projection and be forced downward thereby, thus moving the locking stud 8 downward out of the notch 7. Inasmuch as the receptacle is nor mally held off center, it'will be apparent that as soon as it is unlocked, the receptacle will swing downward to an inverted position so as to permit its contents to drop therefrom.

It is to be understood, of course, that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.

cross bar for shifting the rod upwardly to move thestud into the notch when said notch 15 is brought into register therewith, and means for holding the rod against lateral movement relative to the hanger on Which it is mounted.

In testimony that I claim the foregoing as 20 my own, I have hereto affixed my signature in the presence of tWo witnesses.
